1. THEY DO NOT COMPLAINT ABOUT EACH OTHER TO FRIENDS AND FAMILY
You know the principle: what happens in Vegas, stays in Vegas? The same rule applies in relationships. If you or your loved one finds it necessary to complain to friends or family members about what is happening between you, this is a clear sign that something has gone wrong. In addition, denigrating each other in the eyes of others does not mean solving the problem at all. Better talk to each other - and you may have a chance to save your relationship!

2. THEY DO NOT CRITICIZE EACH OTHER
Being honest about what worries you about your partner is one thing. But criticism is another matter entirely. Happy couples never criticize each other, and at the same time they are frank in their feelings. The difference lies mainly in the “zone of influence”: if criticism is beneficial only to one person, frankness always benefits both parties in the end.

3. THEY DON'T BLAME EACH OTHER
Without accepting responsibility, blaming the other side for everything that goes wrong is a habit that has ruined many love relationships! People in healthy relationships know how to take responsibility for their actions and are able to honestly admit their own mistakes. If you blame your partner for everything, you are bringing the gap closer.

4. They don't take life too seriously
This, of course, does not mean that they live outside of existing social norms. Or that they don't care about anything that happens to them. It just means that they are able to see the bright side where possible and try to experience as many joyful moments together as possible. If you feel like your relationship is getting too serious, just add some humor. It's always helpful...

5. THEY DON'T SAW EACH OTHER
It is easy to grumble at your partner for the slightest reason, but, unfortunately, this is not a very good basis for a harmonious relationship. Endless nagging, constant dissatisfaction or irritation means that the relationship is not developing too correctly. If you want to maintain health and happiness in a relationship, never "nag" your partner. Better encourage...

6. THEY DON'T GUY EACH OTHER
Many people in a relationship don't know how to show their frustration the right way - they try to make the other side feel guilty instead of explaining and teaching the partner to avoid mistakes in the future. Guilt is one of the most dangerous destroyers of happiness in a relationship. Beware!

7. THEY ARE NOT TRYING TO BE WHAT THEY ARE NOT
Society often makes people seem like they are not, and a similar situation develops in relationships. There is a widely accepted, media-invented image of what a happy relationship should look like – and many are trying to emulate it. But the fact is that this image is distorted and not at all tied to real life. This is why happy couples never compare themselves to others and never follow what seems unnatural to them; they are more willing to listen to themselves.

8. THEY NEVER LIE TO EACH OTHER
It's one thing not to "load" your soul mate with everything that's on your mind; the other is an outright lie or deliberate concealment of the truth. The former is actually beneficial for the relationship, as it allows partners to communicate as equals and eliminate parent-child relationships where one has to constantly solve the other's problems. But lying undermines the very foundation of any relationship: trust.

9. THEY DO NOT SLEEP IN DIFFERENT BEDS
Many couples end up sleeping separately after a while, simply because it's more convenient. Maybe one of them snores or maybe they prefer to go to bed at different times and don't want to disturb each other... But whatever the reason, they are making a big mistake. They simply turn a blind eye to the problem instead of solving it. In the end, it all boils down to a simple fact: sleeping in separate beds destroys the feeling of togetherness and intimacy.
